ML Infrastructure Engineer

Openai
San Francisco, CA

About the Team

The Runtime team builds the low level framework components to power our ML training systems. We work on building robust, scalable, high performance components to support our distributed training workloads. Our priorities are to maximize the productivity of our researchers and our hardware, with the goal of accelerating progress towards AGI.

About the Role

As a ML Infrastructure Engineer, you will work on improving the training throughput for our internal training framework, while enabling researchers to experiment with new ideas. This requires good engineering (for example designing, implementing, and optimizing state-of-the-art AI models), writing bug-free machine learning code (surprisingly difficult!), and acquiring deep knowledge of the performance of supercomputers. In all the projects this role pursues, the ultimate goal is to push the field forward.

We’re looking for people who love optimizing performance, understanding distributed systems, and who cannot stand having bugs in their code. Since our training framework is used for large runs with massive numbers of GPUs, performance improvements here will have a large impact.

This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

  • Apply the latest techniques in our internal training framework to achieve impressive hardware efficiency for our training runs

  • Profile and optimize our training framework

  • Work with researchers to enable them to develop the next generation of models

You might thrive in this role if you:

  • Have run small scale ML experiments

  • Love figuring out how systems work and continuously come up with ideas for how to make them faster while minimizing complexity and maintenance burden

  • Have strong software engineering skills and are proficient in Python
